Nah, there are units available in the hundred hertz range, but pricey.
I'm working with a guy who is building GPS telemetry units for use in
model rockets, r/c planes, and other applications (www.gpsflight.com).
He has several units he uses, and told me about some of the other
suppliers he spoke to.  I guess 1hz is pretty much the standard unless
your app is military.  One contact he had was with the people who make
units used in GPS guided Mortar rounds.  Very tough gps units with high
update rate and must survive high accelerations.  Anyways, they're out
there, but they're expensive and you have to jump through hoops to get
them.
